-## Available in Proton 3.7 Beta:
+## Available in Proton 3.16 Beta:
+###### 3.16-1:
+- Rebased Proton patches onto Wine 3.16.
+- Updated Vulkan support in Wine to 1.1.86, plus support for transform feedback.
+- DXVK has been updated to [0.81](https://github.com/doitsujin/dxvk/releases/tag/v0.81) plus support for transform feedback which should fix missing models in many D3D11 games. *Transform feedback requires using Mesa git or NVIDIA's 396.54.09 Vulkan Beta driver*. 
+- DXVK's d3d10 mode is now enabled by default.
+- DXVK is now built as a native Linux library, which may give a small performance boost, and should make debugging easier for DXVK and driver developers.
+- Missing textures for models in some VR games has been resolved.
+- Ask the window manager to bypass the compositor in fullscreen mode. This may improve performance in some situations.
+- All new makefile-based build system.
+## Available in Proton 3.7:
 ###### 3.7-8:
 - Minor compatibility fixes in preparation for future Proton versions.
-## Available in Proton 3.7:
 ###### 3.7-7:
 - Improvements to alt-tab and fullscreen behavior in many games.
 - Fix mouse behavior in some games and mice with high sample rates.
